Thanks for porting 7z-archiver to OS/2. Regarding command-line versions in release of p7zip-16.02-os2-1.zip: It works fine unless drive letters are in use, e.g. "7za.exe l \ArcaOS\Downloads\ArcaOS-5.0.2.iso.7z" is fine, but "7za.exe l C:\ArcaOS\Downloads\ArcaOS-5.0.2.iso.7z" fails by a system error ("Unknown error -2147024872"). Thus, it works for relative paths only! Can you please fix that? Thanks a lot in advance.
